1 Claim.

This is a. division of my application for patent Serial No. 54,301,filed December 13, 1935.

The principal objects of this invention are to provide an improved webguide for strip cellulose or other sheet material; to provide means forproviding the sheet material witha little tension as it enters theguiding device, and to provide guide rolls engaging the web lightly andguide rods between them to feed and guide the web along its course.

Other objects and advantages of the invention will appear hereinafter, I

Reference is to be had to the accompanying drawings, in which Fig. l isan elevation of the machine;

Fig. 2 is an elevation taken in the direction .of the arrow 2 in Fig. 1;

Fig. 3 is a sectional view on the line 33 of Fig. 2;

Fig. i is a plan of the guide for the Cellophane" on the line 6-4 ofFig. 2;

Fig, 5 is a plan of the feed rolls as indicated by the arrow 5 in Fig.3, and

Fig. 6 is a sectional view on the line 6-6 of Fig. 2, showing thecutting knife and stop.

This invention is designed to employ a web of Cellophane or other suchmaterial for packaging tooth-brushes and other brushes. Cellulosederivatives including esters and others and even translucent and opaquematerials can be used. A roll of such material is supported in theproper position and the material is drawn from the roll, properlyguided, and brought into a position in which a plunger can force aseparated sheet of the material into a specially designed former toproduce a package or envelope for receiving the bristles of the brush.

A driving shaft 29 is provided with means, not shown, for driving aparallel shaft 44 intermittently and providing a quick actionwhe theshaft 44 is turning. This is done so that the web can be cut into sheetsat each dwell of the web. The shaft 44 is shown as having a bevel gear43 driving a bevel pinion 41 on a feed roll shaft 48. On the shaft 48is'a gear 49 meshing it can be lifted and placed in open topped bearings"0. This roll is free to rotate but is supplied with an adjustable brakeIll. These feed rolls are for the purpose of drawing the web over a roll5| on a shaft 52 carried by a bracket rolls and constituting guides forthe web.

on the frame. The web passes through a guide and tensioning device 53which comprises a bracket 54 carried in stationary position and apivoted plate 55 which is latched in place by a latch 56. Both thisguide and the bracket are 5 provided with projecting ribs 5'! which donot quite touch but serve to provide a little tension for the web. Thisguide guides the web between two series of vertical rods 58 located ingrooves in the feed rolls which keep the web in place whileitis passingdownwardly. The feed rolls are arranged so that they engage the weblightly but sufficiently to feed it. The guide rods 58 are carried bysupports 59 on one of two former frames 6|. The web is fed down in frontof a stationary plate 62 intermittently. The shaft 29 carries a gear 45constantly driving a sleeve H2, loose on the shaft 44, through a gear46. As the web comes down through the guides 58 it is cut off, at eachdwell, into equal sheets by a 20 pivoted knife blade 65 cooperating witha second cutting surface and operated by a cam 66 on the sleeve H2.When. the cam is out of operation a spring 6'! brings the knife bladeback against an adjustable stop 68. a

The plate 62, against the front of which the severed sheet of Cellophaneor the like is brought from the guides 58, is provided with a shield illhaving a vertical slot H therein. A sliding bar l2, provided with smoothsides, is pushed in through the slot H, which has an. enlarged portionthrough the center to receive the bar I2. The sliding bar I2 constitutesthe means for advancing the sheets out of the guide.

It will be seen that this machine takes a continuous strip of sheetmaterial, of which the envelope is to be made, feeds, it down in frontof an opening, and cuts it off into separate rectangular sheets;

Having thus described my lnvention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claim, but what I claim is:

The combination of a tension guide through which a web passes havinglongitudinal. continuous ribs on opposite sides for lightly engaging theweb at opposite points and applying tension thereto, two series of rodson opposite sides of said web in position to receive the web from thetension guide, and a pair of rolls beyond said guide one made up ofmetal and the other of soft surfaced cylindrical surfaces, half of saidrods passing between the metal. surfaces and the other half between thesoft surfaces of the rolls and both series extending downwardly beyondthe EDWARD F.
